Marsh, James, a Dublin physician and chemist, who distinguished himself by the discovery of a process by which the most minute portions of arsenic can be detected in any body or liquid, was born in 1789. His discovery was given to the world in the Edinburgh Philosophical Journal for October 1836. The process, details of which will be found in the Encyclopaedia Britannica, is constantly made use of in medical jurisprudence. He died at Woolwich, where for some time he had occupied the position of practical chemist to the Royal Arsenal, 21st June 1846, aged 56.
